PBS Eons has a new episode over on Youtube. Why are the majority of humans right-handed? What evolutionary pressures led to it?
No other placental mammal that we know of prefers one side of the body so consistently, not even our closest primate relatives. But being right-handed may have deep evolutionary roots in our lineage. And yet, being a leftie does seem to come with some unexpected advantages.
Big thanks to Julio Lacerda (https://twitter.com/JulioTheArtist) for the excellent right-handed Neanderthal illustrations!
